Wouldn't change.
Any of you ever talk to casuals?
"Oh there's a UFC? WHO'S FIGHTING"
That's what they always ask: "Who's fighting?" And they want to know who's the headliner. That's it.
The answer for this card would be "Anderson Silva." Even though Weidman was the champ. You say "Chris Weidman" people go, "who?" You say "oh he's fighting Anderson" and they're like "ohhh ok. Anderson Siva. Nice."
Ronda's a much bigger star now than ever before. Nowadays, you want people to ask who's on a card and when the answer is "Ronda Rousey," that means a lot more now than it did back then.
